"""Tests for the cookie-domain blast-radius split.

Pins the two-layer contract:

* ``REQUIRED_COOKIE_DOMAINS`` is the default *extraction* set fed to
  rookiepy. This is the canonical enforcement point: sibling-product
  cookies (YouTube, etc.) never reach ``storage_state.json`` unless
  the user opts in via ``--include-domains`` on
  ``notebooklm login`` / ``notebooklm auth refresh`` /
  ``notebooklm auth inspect``.
* The runtime gate consults the full ``REQUIRED ∪ OPTIONAL`` union so
  opted-in cookies survive every downstream filter
  (``convert_rookiepy_cookies_to_storage_state``,
  ``extract_cookies_with_domains``,
  ``build_httpx_cookies_from_storage``).

These tests are split out from ``test_auth.py`` because they cross the
auth/cli boundary — the contracts only make sense as a set.
